For times we don't know WHAT does Heroes' ability affects on
damage spectrum: DPA or DPS. DPA is damage per attack. This is
important as each troop has a different attacking speed. DPS is
damage per second, mean rate of damage for 1 second. This is needed
to be tested... Here is it:

Here is my video which proves that DPA is NOT rounded. The first
cannon that attacked my level 5 Giant (670 HP) deals 15 DPS. As
canons' attack speed is 0.8 seconds it has 12 DPA (no need to be
rounded). It fired 21 hits toward the Giant before being destroyed
by the Giant. The cannon in the upper section is both level 2 (11
DPS, either 8.8, 8, or 9 DPA, being tested). Now the giant is left
with 670 - 252 = 418 HP. The number of total hits from both cannon
to k…

Dragons are really good if you use 8 or more for clan wars, or
even normal attacks. Bring at least a Healng Spell and some Rage
Spells.

You'll attack it on one side which could be close to Air
Defense. The best side to choose is the easiest side to be attacked
for destroying Town Hall. Clear all the buffers on that side using
your other troops, or a Dragon if the Air Defense cannot target it.
The remaining troops should be Archer, Wizard, or a mix of them and
make sure you can destroy all the annoying buffers with them. The
buffer could include Town Hall. Then deploy all your Dragons on the
side.

Deploy Rage Spell everytime the groups of Dragons is vulnerable
to the Air Defense but is not targeting AIr Defense so it quickly
destroy buildings…

If you think that Mortar or Resource Building placed next to
Wizard Tower... I think you are wrong. More specifically
Mortar-Wizard Tower, they can both be destroyed by Lightning
Spells. Okay...

Why do most people like to set an Inferno Tower to multiple
target mode???

Isn't it good to place 2 Inferno Towers close each other with
different mode??? But it could still be bad, except if you sure any
lightning from opponent's lightning spell missed!!! And because of
it's small size, I'm sure. It will happen only if the opponent
brings 5 maxed lightning spells!!! If any lightning missed, the
Inferno Tower will be left with at least 25 HP...
